title: Polymerase chain reaction-based search for two alpha-globin gene mutations in India.
abstract: We have used restriction site-dependent polymerase chain reaction (PCR)-based methodology for detection of the alpha-globin polyadenylation (poly A) signal mutation, AATAAA>AATA- - and Hb Sun Prairie [alpha 130(H13)Ala-->Pro, GCT>CCT (alpha2)] mutation. The former mutation produces Hb H disease in the homozygous state and occurs frequently in the Indian population. It was detected in nine of 77 putative alpha-thalassemia (alpha-thal) patients and in three of 13 beta-thal intermedia patients tested. Four of the nine alpha-thal patients were homozygotes for the mutation. The Hb Sun Prairie mutation was confirmed in two alpha-thal patients, one of whom was a homozygote and the other a heterozygote.
